Focused library approach for identification of new N-acylphenylalanines as VCAM/VLA-4 antagonists

Bioorg Med Chem Lett. 2002 Jun 17;12(12):1679-82. doi: 10.1016/s0960-894x(02)00201-9.

Abstract

A structure-based focused library approach was employed in an effort to identify more lipophilic replacements for the N-benzylpyroglutamyl group of the VCAM/VLA-4 antagonist 2. This effort led to the discovery of two new classes of potent antagonists characterized by the N-(alpha-phenylcyclopentanoyl- and the N-(2,6-dimethylbenzoyl)-derivatives 60 and 64.
